Conditional independence testing is an important problem, especially in Bayesian network learning and causal discovery. Due to the curse of dimensionality, testing for conditional independence of continuous variables is particularly challenging. We propose a Kernel-based Conditional Independence test (KCI-test), by constructing an appropriate test statistic(More)
DNA methylation has been traditionally viewed as a highly stable epigenetic mark in postmitotic cells. However, postnatal brains appear to show stimulus-induced methylation changes, at least in a few identified CpG dinucleotides. How extensively the neuronal DNA methylome is regulated by neuronal activity is unknown. Using a next-generation sequencing-based(More)
Let X denote the feature and Y the target. We consider domain adaptation under three possible scenarios: (1) the marginal P Y changes, while the conditional P X|Y stays the same (target shift), (2) the marginal P Y is fixed, while the conditional P X|Y changes with certain constraints (conditional shift), and (3) the marginal P Y changes, and the(More)
We describe a DNA sequencing technology in which a commonly available, inexpensive epifluorescence microscope is converted to rapid nonelectrophoretic DNA sequencing automation. We apply this technology to resequence an evolved strain of Escherichia coli at less than one error per million consensus bases. A cell-free, mate-paired library provided single DNA(More)
Adenosine-to-inosine (A-to-I) RNA editing leads to transcriptome diversity and is important for normal brain function. To date, only a handful of functional sites have been identified in mammals. We developed an unbiased assay to screen more than 36,000 computationally predicted nonrepetitive A-to-I sites using massively parallel target capture and DNA(More)
A new generation of technologies is poised to reduce DNA sequencing costs by several orders of magnitude. But our ability to fully leverage the power of these technologies is crippled by the absence of suitable 'front-end' methods for isolating complex subsets of a mammalian genome at a scale that matches the throughput at which these platforms will(More)
Genome sequencing currently requires DNA from pools of numerous nearly identical cells (clones), leaving the genome sequences of many difficult-to-culture microorganisms unattainable. We report a sequencing strategy that eliminates culturing of microorganisms by using real-time isothermal amplification to form polymerase clones (plones) from the DNA of(More)
